SAN JUAN, Puerto Rico (AP) - Tropical Storm Gabrielle was downgraded to a depression Thursday as it lashed the U.S. territory of Puerto Rico with heavy rains and swirled toward the Dominican Republic.

The storm was located about 55 miles (90 kilometers) south of Punta Cana, Dominican Republic, in the afternoon and was moving northwest at 9 mph (15 kph) with winds of up to 30 mph (50 kph). It was expected to weaken further in the next two days.

Puerto Rico Gov. Alejandro Garcia Padilla had activated the National Guard, canceled classes at all public schools and closed central government agencies as a precaution.

Heavy rains were still expected across Puerto Rico, according to state meteorologist Ernesto Morales.

"We should not lower our guard," he said. "The storm is very dangerous. There's a very high possibility of flooding."

Falling trees brought down a telephone post in the central town of Ciales, while officials reported small landslides in the central mountain town of Utuado and the southeast town of Yabucoa, with crews working to clear roads. Minor flooding was reported in the island's southeast region.

Several residents in the northern municipality of Bayamon were relocated because a nearby mountain had already experienced landslides in recent weeks amid persistent wet weather.

The storm was expected to drop up to 8 inches (20 centimeters) of rain in central Puerto Rico, and up to 4 inches (10 centimeters) elsewhere in Puerto Rico as well as in the U.S. Virgin Islands and eastern portions of the Dominican Republic. Officials in the U.S. Virgin Islands closed all schools in St. Croix.
